Abstract: A measuring device for contactless detection of an angle of rotation is comprised of a supporting plate (14) made of soft magnetic material which is used as a rotor. In a plane in relation to the supporting plate (14), two segments (16, 17) are disposed, which are separated by means of a slot (21) and a spacer gap (22). The supporting plate (14) is fastened to an axle (11) whose extension (12) or the axle (11) itself is comprised of a magnetically conductive material. The extension (12) protrudes into one of the segments (16) of the stator. The axle (11), particularly its extension (12), the supporting element (14), and the segments (16, 17) control the magnetic flux of the permanent magnet (15) disposed on the supporting plate (14). Through the inclusion of the axle (11) into the magnetic flux, the measuring device is constructed in a relatively simple and space-saving manner.

Abstract: A measuring device for contactless detection of a rotational angle (&agr;) comprises a carrier plate (12), made of soft-magnetic material, which acts as a rotor. Two segments (15, 16) separated by a slit (17) are disposed in a plane parallel to the carrier plate (12). Disposed on one of the segments (16) is a short-circuit piece (20), and all these parts are of soft-magnetic material. The short-circuit piece (20) and the segments (15, 16) serve to guide the magnetic flux that is generated by a permanent magnet (13) disposed on the carrier plate (12). Since the short-circuit piece (20) protrudes past the carrier plate (12), or in a further feature the carrier plate (12) protrudes past the short-circuit piece (20), insensitivity to axial or radial play is possible. Furthermore, the measuring device is relatively simple and space-saving in design.
